Tan=24/10 ≈ 2.4

using Pythagoras theorem

x²=(24)²+(10)²

x²=576+100

x²=57600

x=√57600 => 240

Therefore

sina=24/240 => 0.1

cota=1/tana => 1/(24/10) => 10/24

grin007 [14]

we have

f(x)

and

g(x)=-2f(x)+5

step 1

First transformation

Reflection about the x-axis

f(x) -----> -f(x)

step 2

Second transformation

A vertical dilation with a scale factor of 2

-f(x) ------> -2f(x)

step 3

Third transformation

A translation of 5 units up

-2f(x) -------> -2f(x)+5

The equal statistical measures

See attachment 1 on how to read a box plot

Using attachment 1 as a guide, we have the following observation

Movie 2 Movie 1

$Minimum=7.5$ $Minimum=10$

$Q_1 = 22.5$ $Q_1 = 15$

$Median = 30$

$Q_3 = 35$ $Q_3 = 40$

$Maximum = 47.5$ $Maximum = 52.5$

By comparison, they have equal median (30)
